For the most part, we are the hard core of the fishing world. We live eat breath fishing.
The average angler is a 2 week a year weekend warrior. Don't know the issues and don't care. Like most weekend warriors and their hobbies. See it camping, fishing, skidooing, cycling, golfing, etc... Too busy having fun to worry about the impact they are having. Used to having people clean up after them rather than cleaning up after themselves.
With this prevalent attitude, get used to seeing trash. Get used to seeing angry residents. Get used to seeing restricted access.
Other municipalities take another tack. Automated parking lots and user fees. I've seen the ticket meters in a few fishing locations as well. The sites were downloaded on municipalities that don't want to foot the bill. So visitors now pay.
